Hi vlocker27,

Line 1663 in 1.4.3 is an opening bracket, while in 1.5 beta 6 it is a closing bracket. Do you have an example page which does the error?

Thanks
Allan

I'm using 1.5 B6 as well. Firefox accepts a trailing comma in the JSON string while IE7 complains about it and doesn't parse properly.

Hi Norm,

Good point! I find it very irritating that Firefox allows this. It's not a well formed object if it has a comma followed by an empty element. I would have thought that the Javascript compiler should really throw an error at this point.

I find that jsonLint is exceptionally useful for helping to debug Ajax/Json errors: http://www.jsonlint.com/
